Forward Pass - American and Canadian Football

American and Canadian Football

In American and Canadian football, a forward pass—usually referred to simply as a pass—consists of one offensive player throwing the football towards another downfield in the direction of the opponent's goal line. This is permitted only once during a scrimmage down by the offensive team before team possession has changed, provided the pass is thrown from in or behind the neutral zone. An illegal forward pass incurs a five-yard penalty and the loss of a down, although it may be legally intercepted by the defense and advanced.

If an eligible receiver on the passing team legally catches the ball it is a complete pass and the receiver may attempt to advance the ball. If an opposing player legally catches the ball (all defensive players are eligible receivers) it is an interception. That player's team immediately gains possession of the ball and he may attempt to advance the ball toward his opponent's goal. If no player is able to legally catch the ball it is an incomplete pass and the ball becomes dead the moment it touches the ground. It will then be returned to the original line of scrimmage for the next down. If any player interferes with an eligible receiver's ability to catch the ball it is pass interference which draws a penalty of varying degree (largely depending upon the particular league's rules).

The person passing the ball must be a member of the offensive team, and the recipient of the forward pass must be an eligible receiver and must touch the passed ball before any ineligible player.

The moment that a forward pass begins is important to the game. The pass begins the moment the passer's arm begins to move forward. If the passer drops the ball before this moment it is a fumble and therefore a loose ball. In this case anybody can gain possession of the ball before or after it touches the ground. In Canadian football, if the passer drops the ball while his arm is moving forward it is an incomplete pass (unless someone catches the ball before it hits the ground in which case it is a completed pass or an interception). Under American football's tuck rule, if the quarterback is attempting to bring the ball back to his body after starting a passing motion, a lost ball may be considered an incomplete pass even if the quarterback's arm is moving backward at the time.

The quarterback generally either starts a few paces behind the line of scrimmage or drops back a few paces as the ball is snapped. This places him in an area called the "pocket" which is a protective region formed by the offensive blockers up front and between the tackles on each side. A quarterback who runs out of this pocket is said to be scrambling. Under NFL and NCAA rules, once the quarterback moves out of the pocket, and there is no good option for a forward pass, the ball may be legally thrown away to prevent a sack. NFHS (high school) rules do not allow for a passer to intentionally throw an incomplete forward pass to save loss of yardage or conserve time, except for a spike to conserve time after a hand to hand snap. If he throws the ball away while still in the pocket then a foul called "intentional grounding" is assessed. In Canadian football the passer must simply throw the ball across the line of scrimmage—whether he is inside or outside of the "pocket"—to avoid the foul of "intentionally grounding".

If a forward pass is caught near a sideline or endline it is a complete pass (or an interception) only if a receiver catches the ball in bounds. For a pass to be ruled in bounds, the receiver's feet must be in contact with the in bounds portion of the playing field, or, if the ball is caught in the air, either one or two feet must touch the ground within the field boundaries, after the ball is caught. In the NFL the receiver must touch the ground with both feet, but in most other codes—CFL, NCAA and high school—one foot in bounds is enough.

Common to all gridiron codes is the notion of control—a receiver must demonstrate control of the ball in order to be ruled in possession of it, while still in bounds, as defined by his code. If the receiver catches the ball but the official determines that he was still "bobbling" it prior to the end of the play, then the pass will be ruled incomplete.
